Description

Technical Field

[0001] This invention relates to the field of lathe technology, and more particularly to a lathe debris filtration and collection device. Background Technology

[0002] During the machining process of a CNC lathe, debris will fall off the workpiece. This is due to machining operations such as turning, boring, and cutting. The debris varies in size; larger particles are easier to collect, but smaller particles, being lightweight, are easily carried along by the lubricating oil. Currently, to collect and filter these fine debris so that the filtered lubricating oil can be reused, filter elements are used to remove the debris, thus filtering the lubricating oil.

[0003] When using the above method, because the debris particles are small, the fine debris will adhere to the filter element during filtration, blocking the channels through which lubricating oil can pass. This will cause the filter element to become clogged and unusable, requiring replacement by operators. However, since the filter elements are installed at the bottom of the lubricating oil collection device, it is not easy for operators to observe the clogging. This makes it difficult for operators to inspect and replace the filter elements, and the constant replacement of filter elements will also increase the operating cost of the device. Therefore, a filtration device that can effectively collect debris and extend the service life of the filter element is needed. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The lathe chip filtration and collection device provided by this invention allows chips generated during CNC lathe machining and lubricating oil sprayed onto the workpiece to enter the filtration mechanism. The lubricating oil circulating into the filtration mechanism causes the oil containing chips to flow, and during this flow, the chips are collected by the filter element within the filtration mechanism. Furthermore, the direction of lubricating oil entering and exiting the filtration mechanism can be changed by switching the working state of the steering mechanism: when the lubricating oil flows from the central collection area to the side collection area, the lubricating oil entering the filter collector can wash away the chips adhering to the central filter element, allowing them to then follow the lubricating oil into the side collection area, where the side filter element removes the chips from the lubricating oil. The process involves filtration to remove debris clogging the central filter element, ensuring its proper function. As lubricating oil flows from the side collection area to the central collection area, the oil entering the connecting pipe washes away debris adhering to the side filter elements before flowing into the central collection area, where the central filter element performs filtration. This invention ensures the proper functioning of both the central and side filter elements, effectively filtering debris and guaranteeing the proper use of lubricating oil. Furthermore, it eliminates the need for operator inspection, extends the service life of both filter elements, and reduces the cost of using CNC lathes.

[0018] 2. The lathe chip filtration and collection device provided by this invention, when filtering chips with the central zone filter element and the side filter element, guides the chips into the collection shell and the collection plate respectively, so that the chip collection box collects the collected chips, thereby reducing the chip content in the CNC lathe. This ensures the normal use of the central zone filter element and the side filter element. At the same time, the operator can simply handle the chips in the chip collection box without disassembling the device to replace the central zone filter element and the side filter element, reducing the operator's trouble.

[0050] Example 1

[0051] like Figures 1 to 20As shown, this invention provides a lathe chip filtration and collection device applicable to horizontal CNC lathes. The lathe includes a CNC lathe base 1 and a CNC lathe 2 located above the CNC lathe base 1. The top of the CNC lathe base 1 is open, and the filtration and collection device is located inside the CNC lathe base 1 to collect chips generated during the machining of workpieces by the CNC lathe 2. To extend the service life of the filter element and eliminate the hassle of filter element inspection and replacement, the technical solution adopted by this invention is as follows: the filtration and collection device includes a collection mechanism 3, a filter mechanism 4, a steering mechanism 7, and an oil tank 9; a filter mechanism 4 is respectively provided at both ends of the collection mechanism 3; both the collection mechanism 3 and the filter mechanism 4 are provided with a central collection... The central collection area and the side collection areas located on both sides of the central collection area form a collection space for collecting debris. The side collection areas are connected to the central collection area. The central collection area of ​​the collection mechanism 3 and the central collection area of ​​the filter mechanism 4 are interconnected, and the side collection areas on the same side are also interconnected. The bottom surfaces of the central collection area and the side collection areas of the collection mechanism 3 are both designed with a central protrusion and both sides inclined towards the two ends of the collection mechanism 3, so that the debris generated by the CNC lathe 2 in machining the workpiece and the lubricating oil sprayed on the workpiece can flow into the collection space of the filter mechanism 4 after falling into the collection space of the collection mechanism 3. A lubricating oil inlet and outlet space is also provided below the side collection area of ​​the filter mechanism 4. The filter mechanism 4 is equipped with a useful... A side filter element 12 connects the side collection area and the lubricating oil inlet / outlet space. A chip discharge port is provided at the bottom of the side collection area of ​​the filtration mechanism 4. The side filter element 12 filters debris in the lubricating oil, which is then discharged through the chip discharge port at the bottom of the side collection area of ​​the filtration mechanism 4. A middle filter box 43 is provided at the bottom of the middle collection area of ​​the filtration mechanism 4. A filter collector 11 is installed inside the middle filter box 43. The filter collector 11 includes a middle filter element 113 and a debris receiving cavity. After filtering out debris from the lubricating oil, the middle filter element 113 falls into the debris receiving cavity. The bottom opening of the debris receiving cavity is connected to the chip discharge port at the bottom of the middle filter box 43. The outlet end of the middle filter element 113 is connected to... The oil inlet and outlet ports at the bottom of the intermediate filter box 43 are connected; the two lubricating oil inlet and outlet spaces of the filter mechanism 4 are connected by a connecting pipe 44; each filter mechanism 4 is provided with a corresponding steering mechanism 7, and each steering mechanism 7 is provided with a connecting pipe port, an intermediate filter box port, an oil delivery pump port, and an oil suction pump port; the oil inlet and outlet ports of the connecting pipe 44 and the oil inlet and outlet ports of the intermediate filter box 43 are respectively connected to the connecting pipe port and the intermediate filter box port; an oil delivery pump for delivering lubricating oil in the oil tank 9 to the filter mechanism 4 and an oil suction pump for sucking out the filtered lubricating oil in the filter mechanism 4 to the oil tank 9 are provided between the steering mechanism 7 and the oil tank 9;The oil outlet of the oil pump and the oil inlet of the oil suction pump are respectively connected to the oil pump connection port and the oil suction pump connection port, and the oil inlet of the oil pump and the oil outlet of the oil suction pump are respectively connected to the oil tank 9; the steering mechanism 7 has two working states: in the first working state, the connecting pipe connection port and the oil suction pump connection port, as well as the middle filter box connection port and the oil pump connection port, are respectively connected through the internal channel of the steering mechanism 7; in the second working state, the connecting pipe connection port and the oil pump connection port, as well as the middle filter box connection port and the oil suction pump connection port, are respectively connected through the internal channel of the steering mechanism 7. The channels are connected; the steering mechanism 7 is used to change the direction of lubricating oil entering and exiting the filter mechanism 4 by switching the working state, thereby causing the lubricating oil in the filter mechanism 4 and the collection mechanism 3 to flow, and filtering and collecting debris in the lubricating oil during the flow. At the same time, during the debris collection process, the filter elements (the central filter element 113 and the side filter element 12) in the central collection area and the side collection area of ​​the filter mechanism 4 are flushed, and the filtered debris on the filter elements is flushed off the filter elements to avoid debris clogging the filter elements and making them unusable, thus extending the service life of the filter elements and reducing the frequency of filter element replacement.

[0052] Furthermore, the steering mechanism 7 has four channels inside, which are respectively used to connect the connecting pipe connection port to the oil delivery pump connection port, the connecting pipe connection port to the oil suction pump connection port, the middle filter box connection port to the oil delivery pump connection port, and the middle filter box connection port to the oil suction pump connection port.

[0053] Furthermore, the steering mechanism 7 is used to change the direction of lubricating oil entering and exiting the filter mechanism 4 by switching the working state, thereby causing the lubricating oil in the filter mechanism 4 and the collection mechanism 3 to flow. During the flow of lubricating oil, it will carry debris into the filter mechanism 4, and then filter out and collect the debris through the side filter element 12 and the filter collector 11. Specifically, in the first working state, the flow direction of lubricating oil in the filter mechanism 4 is central collection area - side collection area - lubricating oil inlet and outlet area; In general, lubricating oil enters the middle filter box 43 through the oil pump connection port and the middle filter box connection port via the oil pump pump, and is delivered to the middle collection area of ​​the filter mechanism 4. The lubricating oil flows into the side collection areas and the lubricating oil inlet and outlet areas on both sides. At the same time, the suction pump draws out the lubricating oil in the lubricating oil inlet and outlet areas from the connecting pipe 44 through the suction pump connection port and the connecting pipe connection port. In the second working state, the flow direction of lubricating oil in the filter mechanism 4 is lubricating oil inlet and outlet area - side collection area - middle collection area. Specifically, lubricating oil is pumped through the oil pump, connected to the oil pump port and the connecting pipe port, and enters the connecting pipe 44 to deliver lubricating oil to the lubricating oil inlet / outlet area of ​​the filter mechanism 4. The lubricating oil flows into the side collection area and then into the central collection area. Simultaneously, the suction pump, connected to the suction pump port and the central filter box port, draws out the lubricating oil from the central collection area through the central filter box 43. During this process, as the lubricating oil flows from the central collection area to the side collection area of ​​the filter mechanism 4, it can clear blockages in the central filter area. The debris in the filter element 113 is flushed away, and then the debris in the lubricating oil is filtered through the side filter element 12 in the side collection area. When the lubricating oil flows from the side collection area to the central collection area of ​​the filter mechanism 4, the lubricating oil entering the connecting pipe 44 can flush away the debris attached to the side filter element 12, and then filter through the central filter element 113. By repeatedly flushing the filter elements while filtering and collecting debris, the trouble of inspection by operators can be eliminated, and the service life of the central filter element 113 and the side filter element 12 can be extended.

[0054] Further, the collecting mechanism 3 includes a central collecting shell I 31, and the central collecting area of ​​the collecting mechanism 3 is located inside the central collecting shell I 31; downwardly inclined side plates I 32 are fixed on the outer walls of the central collecting shell I 31 near the center on both sides; a downwardly inclined collecting plate I 35 is fixed on the side of the side plate I 32 away from the central collecting shell I 31; and an upwardly extending side arc plate I 36 is fixed on the side of the collecting plate I 35 away from the side plate I 32; the space enclosed by the outer wall of the central collecting shell I 31 and the side plate I 32, the collecting plate I 35, and the side arc plate I 36 located on the same side is the side collecting area of ​​the collecting mechanism 3; the filtering mechanism 4 includes a central collecting shell II 46, and the central collecting area of ​​the filtering mechanism 4 is located inside the central collecting shell II 46; the central collecting shell II 46 has two sides near the center on both sides. A downwardly inclined side plate II47 is fixed on the outer wall. A downwardly inclined collection plate II410 is fixed on the side of the side plate II47 away from the central collection shell II46. An upwardly extending side arc plate II411 is fixed on the side of the collection plate II410 away from the side plate II47. The space enclosed by the outer wall of the central collection shell II46 and the side plate II47, the collection plate II410 and the side arc plate II411 located on the same side is the side collection area of ​​the filter mechanism 4. The central collection shell II46, the side plate II47, the collection plate II410 and the side arc plate II411 correspond one-to-one with the central collection shell I31, the side plate I32, the collection plate I35 and the side arc plate I36 respectively and are connected to each other at the end face. The side arc plate I36 is connected to the outer side of the side arc plate II411 by a connecting plate.

[0055] Furthermore, the bottom surface of the central collection shell I31, the side inclined plate I32, and the collection plate I35 are all structures with a central protrusion and both sides inclined towards the two ends of the collection mechanism 3. The cross-section can be regarded as an inverted V-shaped structure. This structure can guide the debris and lubricating oil entering the collection mechanism 3 to the filter mechanism 4, so that the debris and lubricating oil can be easily filtered by the filter mechanism 4.

[0056] Furthermore, a guide arc plate I34 is fixed at the upper end of the side arc plate I36, extending towards the central collection shell I31 at one end. The other end of the guide arc plate I34 extends beyond the upper end of the central collection shell I31 and reaches above the central collection area of ​​the collection mechanism 3. The end of the guide arc plate I34 above the central collection area of ​​the collection mechanism 3 is higher than the vertical height of the upper end of the central collection shell I31. A guide arc plate II49 is fixed at the upper end of the side arc plate II411, extending towards the central collection shell II46 at one end. The other end of the guide arc plate II49 extends beyond the upper end of the central collection shell II46 and reaches the middle of the filter mechanism 4.

[0057] Furthermore, the middle filter box 43 is installed on the bottom surface of the middle collection shell II 46; the lower end of the side arc plate II 411 is fixed with a side bottom plate 45, and the other end of the side bottom plate 45 is fixed to the outer side wall of the middle collection shell II 46. The space enclosed by the outer side wall of the middle collection shell II 46, the side inclined plate II 47, the collection plate II 410 and the side bottom plate 45 located on the same side is the lubricating oil inlet and outlet space of the filter mechanism 4.

[0058] Furthermore, the side of the filter mechanism 4 away from the collection mechanism 3 is sealed by a sealing plate 41, and the side of the lubricating oil inlet / outlet space near the collection mechanism 3 is sealed by a blocking plate 42. The central collection shell I 31, the side inclined plate I 32, and the collection plate I 35 are fixed to the blocking plate 42 by screws.

[0059] Furthermore, the central collection shell I 31 and the central collection shell II 46 are U-shaped structures, the collection plate I 35 and the collection plate II 410 are provided with upward-opening grooves, and the bottom of the collection plate II 410 is provided with a chip discharge port; the side inclined plate II 47 is provided with an installation port, and the side filter element 12 is installed in the installation port. The side filter element 12 connects the side collection area with the lubricating oil inlet and outlet space.

[0060] Furthermore, the filter collector 11 also includes a collection shell 111. The shape of the upper surface of the collection shell 111 is adapted to the bottom shape of the middle collection shell II 46. The collection shell 111 has a through-hole extending vertically. The size of the upper through-hole of the collection shell 111 is larger than that of the lower through-hole. An installation tube 112 is fixedly installed inside the collection shell 111. During installation, the installation tube 112 enters the collection shell 111 from the upper side through the through-hole and is then fixed to the bottom of the collection shell 111 with screws. The installation tube 112 has an axial opening, and its upper and lower ends are respectively connected to the upper and lower through-holes of the collection shell 111. The middle zone filter element 113 is installed inside the installation tube 112.

[0061] Furthermore, in this embodiment, the side filter element 12 and the central filter element 113 have specific filter element structures.

[0062] like Figure 8 and Figure 9 As shown, the side filter element 12 is square with a serrated upper surface, and the serrated creases face the collection plate I 35. When the side filter element 12 is installed in the mounting port, it is tilted towards the collection plate I 35. When the side filter element 12 filters the lubricating oil, after filtering out the debris in the lubricating oil, some of the debris will move towards the collection plate I 35 along the tilting direction of the serrated creases, causing the debris to accumulate in the collection plate I 35, thereby reducing the debris content on the side filter element 12.

[0063] like Figures 13 to 15As shown, the central zone filter element 113 is cylindrical, and the top side of the central zone filter element 113 and the top of the mounting tube 112 are provided with mutually compatible outwardly inclined serrated structures. When the central zone filter element 113 is installed in the mounting tube 112, the serrated structures on the central zone filter element 113 correspond to the serrated structures on the mounting tube 112. When the central zone filter element 113 filters debris in the lubricating oil, the serrated structures on the central zone filter element 113 can guide some debris onto the serrated structures of the mounting tube 112, and guide the debris into the debris receiving cavity between the collection shell 111 and the mounting tube 112 for collection.

[0064] Furthermore, to facilitate the installation of the side filter element 12 and the central filter element 113, the side filter element 12 is fixed to the side inclined plate II 47 by screws. The side wall of the central filter element 113 is provided with several inverted L-shaped grooves spaced circumferentially. Several pins corresponding to the grooves are fixed on the inner wall of the mounting tube 112. When the central filter element 113 is inserted into the mounting tube 112, the pins extend into the corresponding grooves and slide along the vertical part of the grooves. When the pins move to the top of the grooves, the central filter element 113 is rotated, and the pins move to the horizontal part of the grooves. At this time, the central filter element 113 can be fixed inside the mounting tube 112.

[0065] Furthermore, the end faces of the central collection shell I31, the side inclined plate I32, and the collection plate I35 are provided with a plurality of fixing ears. The central collection shell I31, the side inclined plate I32, and the collection plate I35 are fixed to the sealing plate 42 by screws in conjunction with the fixing ears. A rubber gasket is installed on the contact surface between the collection mechanism 3 and the filter mechanism 4 for sealing. The outer side of the side arc plate I36 and the side arc plate II411 are connected by a connecting plate. One side of the connecting plate can fit against the outer side wall of the side arc plate I36 and the side arc plate II411, and both ends are fixed to the side arc plate I36 and the side arc plate II411 by screws respectively.

[0066] Furthermore, the device of the present invention tightly connects the collection mechanism 3 and the filtering mechanism 4 together, so that the collection space formed by the combination of the collection mechanism 3 and the filtering mechanism 4 is a space with an upper opening, so as to collect the debris cut by the CNC lathe 2.

[0067] Furthermore, such as Figures 16 to 20As shown, the steering mechanism 7 includes a steering box 71, a steering column 73 rotatably mounted inside the steering box 71, and a sealing cover 72 fixed to one side of the steering box 71 to seal the steering column 73 inside the steering box 71. The outer side wall of the steering column 73 is in sliding contact with the side walls of the steering box 71 and the sealing cover 72, respectively. A servo motor 13 is fixed to the steering box 71 via a connecting bracket. The steering column 73 is provided with a steering shaft passing through the sealing cover 72. The output shaft of the servo motor 13 and the steering shaft are connected by a coupling. The servo motor 13 is connected to drive the steering column 73 to rotate; the connecting pipe port, the middle filter box port, the oil supply pump port, and the oil suction pump port are all located on the side wall of the steering box 71, with the connecting pipe port and the middle filter box port on the same side, and the oil supply pump port and the oil suction pump port on the opposite side; the connecting pipe port and the middle filter box port are symmetrically arranged with the oil supply pump port and the oil suction pump port along the axis of the steering column 73. The distance between the connecting pipe port and the middle filter box port is the same as the distance between the oil delivery pump port and the oil suction pump port; the steering column 73 has four channels inside, two straight channels 74 and two inclined channels 75; the two straight channels 74 are arranged between the two inclined channels 75, and the straight channels 74 and the inclined channels 75 penetrate the steering column 73 and form eight connection ports on the side wall; the distance between the two connection ports of the two straight channels 74 on one side of the steering column 73 is the same as the distance between the connecting pipe port and the middle filter box port, and the distance between the two ports on the other side is the same as the distance between the oil delivery pump port and the oil suction pump port; the distance between the two connection ports of the two inclined channels 75 on one side of the steering column 73 is the same as the distance between the connecting pipe port and the middle filter box port, and the distance between the two ports on the other side is the same as the distance between the oil delivery pump port and the oil suction pump port; the two inclined channels 75 are inclined inside the steering column 73, and their specific inclination is as follows: Figure 20As shown, the two inclined rails 75 are arranged with their four connection ports on the steering column 73 facing each other in a cross pattern. Driven by the servo motor 13, the steering mechanism 7 switches between two working states by rotating the steering column 73: In the first working state, the two connection ports of one of the straight rails 74 are connected to the connecting pipe connection port and the oil suction pump connection port, respectively, and the two connection ports of the other straight rail 74 are connected to the middle filter box connection port and the oil delivery pump connection port, respectively; In the second working state, the two connection ports of one of the inclined rails 75 are connected to the connecting pipe connection port and the oil delivery pump connection port, respectively, and the two connection ports of the other inclined rail 75 are connected to the middle filter box connection port and the oil suction pump connection port, respectively; When the steering mechanism 7 switches between the two working states, the rotation angle of the steering column 73 is 90°.

[0068] Furthermore, a mounting frame 6 is provided below the collection mechanism 3. The mounting frame 6 is used to support the collection mechanism 3, so that the collection mechanism 3 can be stably set up during use. The mounting frame 6 includes a frame formed by a combination of several connecting rods 61. The oil tank 9 is installed inside the frame. Several receiving plate frames 62 are connected to the upper side of the frame by screws. The receiving plate frames 62 have grooves that are adapted to the bottom of the middle collection shell I 31. The middle collection shell I 31 is installed in the grooves. The middle collection shell I 31 is supported by several receiving plate frames 62, so that the middle collection shell I 31 can be stably placed during use.

[0069] Furthermore, the chip discharge port at the bottom of the collecting plate II 410 and the chip discharge port at the bottom of the middle filter box 43 are respectively equipped with a drain pipe, and the other end of the drain pipe is connected to the chip collection box 8, which is used to collect the filtered chips; the drain pipe at the bottom of the collecting plate II 410 passes through the side bottom plate 45.

[0070] Furthermore, receiving frames 64 are symmetrically fixed on both sides of the frame composed of several connecting rods 61, and the debris collection box 8 connected to the drain pipe on the collection plate II 410 is placed on the receiving frames 64; a fixing frame 63 is fixed near the side wall of the frame, the turning box 71 is fixed to one side of the fixing frame 63 by screws, and the debris collection box 8 connected to the drain pipe on the middle filter box 43 is placed on the fixing frame 63.

[0071] Furthermore, such as Figure 2 and Figure 3 As shown, in Figure 3 The filter collection device shown is equipped with a protective plate on its outer side. After the protective plate is installed, as shown... Figure 2As shown, the protective plate protects the filter collection device inside, and a door panel is hinged to the protective plate at the position corresponding to the debris collection box 8. The debris collection box 8 can be taken out by opening the door panel.

[0072] When the filter collection device of the present invention is in use:

[0073] When the CNC lathe 2 is machining the workpiece, the debris on the workpiece falls into the middle collection area of ​​the collection mechanism 3. At the same time, when the CNC lathe 2 is cutting the workpiece, it can spray lubricating oil onto the workpiece to cool it down. Meanwhile, the debris on the workpiece flows into the middle collection area of ​​the collection mechanism 3 along with the lubricating oil. The collection mechanism 3 can guide the lubricating oil and debris towards the filter mechanism 4. When in use, the collection space of the collection mechanism 3 is filled with lubricating oil, and its liquid level is higher than the upper end of the middle collection shell I 31. In order to reduce the amount of lubricating oil in the middle collection area of ​​the collection mechanism 3, a reducing tank 5 is installed inside the middle collection area of ​​the collection mechanism 3. The reducing tank 5 is fixed between the two sealing plates 41 on both sides by screws. A gap is left between the reducing tank 5 and the side wall of the middle collection shell I 31 for the lubricating oil to flow.

[0074] By switching the working state of the steering mechanism 7, the direction of the lubricating oil entering and exiting the filter mechanism 4 is changed, thereby causing the lubricating oil in the filter mechanism 4 and the collection mechanism 3 to flow. During the flow of the lubricating oil, the debris in it will be carried through the side filter element 12 and the filter collector 11 to filter out the debris and collect it.

[0075] Steering mechanism 7 in its first working state, such as Figure 21 As shown, the flow direction of lubricating oil in the filter mechanism 4 is: central collection area - side collection area - lubricating oil inlet and outlet area: the oil pump delivers the lubricating oil in the oil tank 9 to the steering mechanism 7, at which time the two straight sections 74 of the steering column 73 ( Figure 20In sections a and b), the two connecting ports of one straight channel 74 are connected to the connecting pipe and the oil suction pump connecting port, respectively, and the two connecting ports of the other straight channel 74 are connected to the intermediate filter box connecting port and the oil delivery pump connecting port, respectively. Lubricating oil supplied from the oil delivery pump to the steering mechanism 7 is delivered to the intermediate filter box 43 via straight channel 74 (marked as a). The lubricating oil entering the intermediate filter box 43 enters the intermediate filter element 113 through the opening at the bottom of the collection shell 111. The lubricating oil entering the intermediate filter element 113 impacts the metal debris attached to the upper end of the intermediate filter element 113, causing the debris to detach from the intermediate filter element 113. Some of the debris detached from the intermediate filter element 113 enters the debris receiving cavity between the collection shell 111 and the mounting pipe 112, and is discharged through the drain. The pipe enters the debris collection box 8, and some debris flows upward with the lubricating oil, passing the top of the central collection shell II 46 and entering the side collection area. It is then filtered by the side filter element 12. The filtered lubricating oil enters the lubricating oil inlet and outlet space, while the debris filtered by the side filter element 12 gathers on the upper side of the side filter element 12. Some debris is guided into the collection plate II 410 along with the inclined side filter element 12, and then enters the debris collection box 8 through the drain pipe. At this time, the lubricating oil in the steering mechanism 7 is absorbed by the suction oil pump connected to the same filtration mechanism 4, so that the lubricating oil entering the lubricating oil inlet and outlet space enters the straight channel 74 marked b in the steering mechanism 7 through the connecting pipe 44, and then is absorbed into the oil tank 9 by the suction oil pump through the pipeline.

[0076] When it is necessary to switch the working state of the steering mechanism 7 to the second working state, the steering column 73 is rotated 90° by the servo motor 13, such as... Figure 22 As shown, the flow direction of lubricating oil in the filter mechanism 4 is lubricating oil inlet / outlet area - side collection area - central collection area; in the second working state, the two inclined tracks 75 of the steering column 73 ( Figure 20In sections c and d), the two connecting ports of one inclined duct 75 are respectively connected to the connecting pipe port and the oil pump port, and the two connecting ports of the other inclined duct 75 are respectively connected to the middle filter box port and the suction oil pump port. The lubricating oil supplied from the oil pump to the steering mechanism 7 is supplied to the connecting pipe 44 through the inclined duct 75 marked d, and then the lubricating oil is supplied to the lubricating oil inlet and outlet space through the connecting pipe 44, and then enters the side collection area through the side filter element 12. During the process of the lubricating oil passing through the side filter element 12, the debris attached to the upper side of the side filter element 12 is washed away, and some debris will flow into the collection plate II 410 and be collected by the debris collection box 8, and enter the... The lubricating oil in the side collection area can also carry some debris over the top of the central collection shell II 46 and into the central collection area. After the lubricating oil enters the collection shell 111, the central filter element 113 filters the lubricating oil. Some of the filtered debris adheres to the central filter element 113, while some is guided by the top of the central filter element 113 and the mounting pipe 112 into the debris receiving cavity between the collection shell 111 and the mounting pipe 112, and then collected by the debris collection box 8. The lubricating oil passing through the central filter element 113 accumulates in the central filter box 43. At this time, the oil pump connected to the same filtration mechanism 4 absorbs the lubricating oil in the steering mechanism 7, causing the accumulated oil to accumulate in the central filter box 43. The lubricating oil in the middle filter box 43 enters the inclined channel 75 marked "c" in the steering mechanism 7, and is then drawn into the oil tank 9 by the oil suction pump through a pipeline. Simultaneously, to reduce the amount of debris entering the middle collection area, a downwardly inclined baffle plate I33 is fixed in the middle of the side arc plate I36 facing the middle collection shell I31 in the collection mechanism 3; a downwardly inclined baffle plate II48 is fixed in the middle of the side arc plate II411 facing the middle collection shell II46 in the filter mechanism 4. A space is formed between the baffle plate I33 and the side arc plate I36, and between the baffle plate II48 and the side arc plate II411, respectively. The baffle plate I33 and the baffle plate II48 can prevent the lubricating oil from being carried away. Moving debris flows upward; in the collection mechanism 3, the baffle plate I 33 can guide the lubricating oil in the side collection area to the two side filter mechanisms 4; when the steering mechanism 7 switches to the second working state, in the filter mechanism 4, when the lubricating oil carries the debris upward, some of the lubricating oil will be guided by the baffle plate II 48 to move towards the side arc plate II 411. The lubricating oil that enters between the baffle plate II 48 and the side arc plate II 411 is blocked from flowing by the baffle plate II 48, and some of the debris carried in the lubricating oil will fall into the collection plate II 410 by sedimentation. This method can reduce some of the debris in the lubricating oil, thereby reducing the debris content entering the middle collection area from the side collection area.

[0077] The flow direction of lubricating oil in the central and side collection zones is controlled by the filtration mechanism 4. When the lubricating oil flows from the central collection zone to the side collection zone, the lubricating oil entering the filter collector 11 washes away the debris attached to the central filter element 113. The lubricating oil then flows into the side collection zone, where the side filter element 12 filters the debris in the lubricating oil, thereby removing the debris clogging the central filter element 113 and ensuring its normal operation. When the lubricating oil flows from the side collection zone to the central collection zone... When in operation, the lubricating oil entering the connecting pipe 44 washes away the debris attached to the side filter element 12, and then follows the lubricating oil into the central collection area, where the central filter element 113 performs filtration. The above method ensures the normal use of the central filter element 113 and the side filter element 12, allowing both to effectively filter debris and ensuring the normal use of lubricating oil. At the same time, this method also eliminates the trouble of operator inspection, extends the service life of the central filter element 113 and the side filter element 12, and reduces the operating cost of CNC lathes.

[0078] It should be noted that during operation, the direction of lubricating oil flow in the two filter mechanisms 4 at both ends of the collection mechanism 3 remains the same; Figure 21 and Figure 22 Solid arrows indicate the direction of lubricating oil flow, while hollow arrows indicate the direction in which debris enters the debris collection box 8. During the flow of lubricating oil, larger debris particles generated by the CNC lathe 2 enter the collection shell 111 after entering the central collection area. The flow of lubricating oil does not affect the large debris particles, which cannot be suspended by the flow of lubricating oil, while small debris particles can be suspended by the flow of lubricating oil. When the lubricating oil flows, the flow speed is slow, which allows the side filter element 12 and the central filter element 113 to effectively filter the oil. However, if the flow speed is too fast, the lubricating oil will carry away some debris when passing through the side filter element 12 and the central filter element 113.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
